Tuesday 03/25/14

Incoming continental haze with elevated fine particulate background levels combined with light morning and evening winds should help raise the daily PM2.5 AQI into the "Moderate" range in the Houston area, with highest concentrations in the morning and evening. Background levels due to the continental haze should also be high enough for the daily PM2.5 AQI to remain at the upper end of the "Good" range across the eastern half of the state, with a few spots reaching "Moderate" levels. Elsewhere in the state, moderate winds and lower incoming background levels should help to keep air quality in the "Good" range.

Afternoon winds may be strong enough to generate blowing dust in parts of far West Texas including the El Paso area, but the duration and intensity are not likely to be enough to raise the daily PM10 AQI beyond the "Good" range. Elsewhere in the state, moderate winds and low incoming background levels should help to keep air quality in the "Good" range.
